✓ Two cases are presented in which clip occlusion of a third distal anterior cerebral artery segment occurred during treatment of anterior communicating artery aneurysms. Case histories, angiograms, operative descriptions, and postmortem findings are presented. The incidence of this anomalous vessel is reviewed. Preoperative and intraoperative vigilance in determining the presence of this anomaly prior to clip placement is emphasized.

Saccular Aneurysms

✓ A series of 13 patients with saccular aneurysms of the distal anterior cerebral artery, operated on by the same surgeon with microtechniques, is reviewed. The incidence of aneurysms in this location was 3.4%, the median age of the patients 44 years, and the median time from most recent hemorrhage to surgery 13 days. There were five cases of multiple aneurysms. No operative mortality occurred; the operative morbidity was 15%. Because of their multiplicity, characteristic broad base, and the small subarachnoid space in the interhemispheric fissure, these aneurysms are judged technically difficult.

✓ The angiographic and anatomical features of an anomalous communication between the intradural internal carotid artery and the anterior cerebral artery are described. Essential features of the anastomosis include an origin at, or close to, the origin of the ophthalmic artery, a course ventral to the ipsilateral optic nerve and anterior to the optic chiasm, and a termination near the anterior communicating artery. Although rare, the condition should be considered as an entity. The incidence of associated berry aneurysm and other congenital vascular anomalies is high.

✓ The effect of removal of the left superior cervical ganglion on the contractile response to norepinephrine (NE) and 5-hydroxytryptamine (5-HT, serotonin) was studied in isolated segments of the middle cerebral artery (MCA) and posterior communicating artery (PCoA) of the cat. Fifteen days after the excision, each dose of NE elicited a potentiated response in both the MCA and the PCoA, whichever side they originated. By contrast, 5-HT induced enhanced vasoconstriction at each dose only in the MCA and PCoA from the left side. When segments of MCA and PCoA from the right side were challenged against 5-HT, a significantly increased response was found only at the first three doses. On the other hand, the NE content of pools made of MCA, PCoA, and anterior cerebral artery from each side was reduced to the same level on both sides after ganglion removal. These results indicate that the excised superior cervical ganglion innervated the MCA and PCoA from both sides of the circle of Willis.

✓ The authors present the case of a patient with a pituitary tumor, who manifested signs of subarachnoid hemorrhage (SHA) and loss of consciousness. After he had regained consciousness, massive left-sided paralysis was noted. Angiography and computerized tomography showed hemorrhage into the tumor, SAH, and ischemia of the right frontal lobe as a result of occlusion of the anterior cerebral artery. Removal of the tumor 3 weeks after the SAH did not lead to resumption of the anterior cerebral artery blood flow.

✓ A case of a giant anterior cerebral artery fusiform aneurysm is presented. The lesion was treated by primary excision of the involved segment with an end-to-end anastomosis of the proximal-distal segments of the anterior cerebral artery. It is believed that this technique has not been reported previously for lesions involving major intracranial arteries.

✓ Two patients with rare variations of the A1 segment of the anterior cerebral artery are presented.

The authors present a summary of A1 segment variations described in the literature.

✓ A 3- to 10-year follow-up of a selected group of 23 patients treated for ruptured anterior communicating aneurysms by proximal clipping of one anterior cerebral artery has been evaluated. There was no instance of recurrent hemorrhage. The operation carried a relatively low morbidity and mortality (13%). Early and late results are compared. The importance of adequate preoperative angiography, the minimal complications, and the advantages of the procedure are discussed.
